Senator needs a water break: Marco Rubio drinks during State of the Union rebuttal

Florida Sen. Marco Rubio, delivering the Republican response to President Barack Obama's State of the Union Address Tuesday, urged Obama to "abandon his obsession with raising taxes" and said the president had shifted the nation away from free-market economic principles that had helped middle-class families achieve prosperity.

"Presidents in both parties — from John F. Kennedy to Ronald Reagan — have known that our free-enterprise economy is the source of our middle-class prosperity. But President Obama? He believes it's the cause of our problems," Rubio said.

Rubio appeared to wipe away sweat during his rebuttal from the Speaker's conference room in the U.S. Capitol. At one point, he reached out with his left hand and took a small swig from a Poland Spring water bottle. As the incident generated heavy attention on Twitter, Rubio later tweeted a photo of the water bottle.
